Leydig, Voit & Mayer, LTD.

Leydig, Voit & Mayer, LTD., a for-profit intellectual property law firm headquartered in Chicago, Illinois, operates as a prime contractor providing specialized patent legal services to federal research agencies with no reliance on subcontractors. The firm competes in full-and-open procurement without set-aside designations, reflecting the specialized technical expertise required for its work.

Leydig, Voit & Mayer delivers comprehensive patent prosecution and intellectual property counsel across biotechnology, chemistry, mechanical engineering, and software domains. Representative work includes a $888,800 time-and-materials delivery order with the National Cancer Institute for mechanical engineering patent legal services (completion June 2027), a $1,377,180 task order with NCI for chemistry patent services (completion June 2027), and an $8,888,000 delivery order with NCI for biotechnology patent legal services (completion June 2027). The firm's services encompass preparing and filing patent applications, conducting prior art searches, patent prosecution, conflict-of-interest reviews, and general intellectual property counsel. Recent smaller delivery orders include preparing and filing provisional, national-stage, and Patent Cooperation Treaty applications for NHLBI, NIDDK, NIAID, NHGRI, NIBIB, NINDS, and NCATS.

Customer concentration is extreme and singular: the National Institutes of Health accounts for the overwhelming majority of the firm's federal footprint. The top three customers by award count — NIH Office of Logistics and Acquisition Operations (2,522 awards, $1.08 billion), NIH Office of the Director (2,258 awards, $19.5 million), and NIH (332 awards, $8.73 billion) — collectively represent 94% of recent awards. By dollar value, NIH entities dominate even more starkly, with the agency and its offices accounting for approximately 70% of combined potential value. This concentration reflects Leydig, Voit & Mayer's position as a principal legal service provider to the NIH's patent portfolio, which the firm's award descriptions note encompasses nearly 2,500 active cases and 200–300 new patent applications filed annually.

The firm holds multiple seats on the NIH Patent Legal Services master IDIQ contract, a $552 million vehicle issued in April 2020 covering four technology categories: biotechnology ($386 million), chemistry ($115 million), mechanical engineering ($17 million), and software ($17 million). This single parent vehicle generated 158 task orders valued at $24.9 million across the firm's recent award footprint. Two additional indefinite-delivery contracts — HHSN263200900008I (3,127 task orders, $23.7 million) and HHSN263200900023I (1,510 task orders, $9.3 million) — represent ancillary volume, though their scope and customer agencies are not detailed in the source.

Activity has grown modestly year over year: 17 awards in 2022, 22 in 2023, 32 in 2024, and 25 in 2025, with one award recorded to date in 2026. Sixteen awards (combined potential value $12.4 million) face ultimate completion within the next twenty-four months and therefore present recompete exposure.

Service Contract Inventory captures SCI-reportable invoicing of $9.6 million across FY2022–FY2024, with FY2022 at $2.7 million (2.2 FTEs), FY2023 at $3.4 million (2.6 FTEs), and FY2024 at $3.4 million (2.7 FTEs). On federal services contracts captured in SCI, government-paid rates ran median $550.53 per hour, with a 10th percentile floor around $454.64 per hour and 90th percentile ceiling around $648.96 per hour. The firm delivers all work from its Chicago headquarters with no named subcontractors across its SCI-reportable federal portfolio. Award categorization is highly concentrated: 5,108 awards fall under NAICS 541110 (Offices of Lawyers), with 5,496 awards assigned PSC code for Support–Professional: Legal.
